A method for bearing a multi-protocol label switching, MPLS, packet in a passive optical network, PON, a receiving method, an optical network unit, ONU,/optical network terminal, ONT,/optical line terminal, OLT, and a communication system are provided, which relate to an optical communication network, and are designed to solve the technical problem that protocol stack layers are complicated when a PON and a mobile network are coupled. The sending method includes the following steps. An MPLS packet is obtained. The MPLS packet is encapsulated into a Gigabit PON, GPON, encapsulation mode, GEM, frame. The GEM frame is sent. The receiving method includes the following steps. A GEM frame is received. The GEM frame is decapsulated into an MPLS packet. The MPLS packet is sent. Therefore, tight coupling between the PON and the mobile network is realized. |
